Cucumber sowing time and method

In recent years, although cucumbers grown in greenhouses have high yields, their taste is often not as crisp and refreshing as those grown in the field . Therefore, some growers have begun to return to traditional open-field cultivation methods to meet the market demand for high-quality vegetables by producing pure natural green cucumbers. Let’s learn the time and method of sowing cucumbers.

1. Cucumber sowing time

The planting time for cucumbers is generally from January to March in spring or from June to August in summer and autumn. When planting in spring, you can soak the seeds for germination and then grow seedlings, or you can directly sow them by covering them with mulch. In summer and autumn, both soaking and dry planting are feasible. You can also choose to plant in different environments such as open field, spring greenhouse, spring greenhouse , autumn greenhouse, winter greenhouse, etc. according to the characteristics of the variety.

1. Seed selection and soaking

When growing cucumbers in a greenhouse, you should choose high-quality varieties that are cold-resistant and disease-free. When building a seedbed, choose a dry, ventilated, well-drained plot of land that has not been planted with eggplant vegetables, and prepare nutrient soil with a soil to fertilizer ratio of 7:3. Add a small amount of trace elements, stir evenly, and then pour in bottom water. Soak the seeds in hot water at 50-60℃, stir slowly until the water temperature drops to about 30℃, continue soaking for 6 hours, take out, dry, and spray the new lipid membrane solution.

2. Prepare for planting

Reasonable fertilization: Apply base fertilizer about 15 days before planting to ensure a reasonable combination of nutrients, the ratio of nitrogen, phosphorus and potassium is about 1:0.25:1, and then water the base.

Covering and insulation: Due to the low temperature in winter, double-layer greenhouse film and triple-layer film are needed. Spraying the ground and cucumber plants with new lipid film will help to keep warm and prevent diseases and pests. Proper ventilation should be carried out according to temperature changes every day to keep the temperature in the greenhouse at about 25°C.

Water and fertilizer management: After planting, water and fertilize appropriately according to the temperature and growth conditions to ensure balanced nutrition.

3. Promote flowering and fruiting

After the plant resumes normal growth, spray flower-promoting agents in time to inhibit excessive growth of main and lateral buds and promote flower bud differentiation. Spray the cucumber's bone-strengthening agent during the bud stage, young fruit stage, and fruiting stage to promote fruit development and improve cucumber quality and yield.

4. Pest and disease control

When cucumbers are planted in greenhouses in winter, the main diseases include anthracnose, powdery mildew, black spot, angular spot, mosaic disease, downy mildew virus, wilt virus, etc., which can be prevented and controlled by agricultural streptomycin, thiophanate-methyl wettable powder, new lipid film solution, etc.

The above is an introduction to the sowing time and method of cucumbers. As a common vegetable, cucumber has a large market demand. We must master the methods to increase yield.
